JOSEPH G. DES ROBERTS, OF PORTSMOUTH, NEW HAMPSHIRE.

IRREVERSIBLE STEERING Application filed November To all whom it may concern:

Be it known that I, JOSEPH G. Dns ROBERTS, a citizen of the United States, residing at Portsmouth, in the county of Rockingham and State of New Hampshire, have invented a new and useful Irreversible Steering Device for Automobiles, of which the following is a specification.

Fig. 1 is a plan view of the male disc member.

Fig. 2 is a side view of the male disc member.

Fig. 3 is a plan view of the female disc member.

Fig. 4 is a side View of the female disc member.

Fig. 5 is a view showing the position of the device with relation to the steering wheel.

The invention consists of a device constructed from two circular discs of spring steel, case hardened, each approximately 2% in diameter, and in thickness.

The discs are of the male'and female type respectively; the male disc being called the A disc, and the female disc being called the B disc.

The male disc A has nine projections, 1, produced by either the insertion of rivets or by stamping, concentric with the center of the disc on a radius of approximately 1%,, spaced equally on the circle. The A (male) disc has a 1 hole in the center.

The B (female) disc has eighteen (18) countersunk holes, 2, equidistant, concentric with the center of the disc, on the same radius from the center of the disc as the projections on the A (male) disc. The B (female) disc has gear teeth 3, cut in the center to engage and mesh with the gears in the steering wheel of a Ford automobile.

The A (male) disc has three holes, 4, approximately in diameter, equally spaced on the circle approximately 1% digmeter, concentric with the center of the DEVICE FOR AUTOMOBILES.

25, 1924. Serial N0. 752,270.

The A (male) disc is slipped on the three pins on the steering post on top of the three small gears in the steering mechanism of a Ford automobile. The B (female) disc is next placed on top of the A (male) disc, the gear teeth 3, onthe inner edge of the B (female) disc engaging and meshing with the gears in the steering wheel.

The three pins of the steering gear hold the A (male) in a permanent position. The gear of the steering wheel turns the B (female) disc by engaging the gear teeth out on the inner circle of same. The nine projections 1, of the A (male) disc matching the eighteen holes 2, in the outer edge of the B (female) disc lock the steering mechanism in a secure and rigid position thereby enabling the operator to drive and guide the Ford auto-mobile free from an noyance caused by roughness and irregularity in thesurface of the highway.

The spring of the steel allows the two discs to turn against each other when the steering wheel is turned by the operator.

I claim:

In combination with a steering mechanism of the planetary gear type, having a sun gear and three planet gears, a. stabilizing device comprising a disk having a central aperture provided with teeth to engage the teeth of the sun gear, said disk having a plurality of equally spaced countersunk recesses equidistant from the center of the disk; a second disk provided with three apertures adapted to be fitted on the shafts of the three planet gears, said second disk having a plurality of equally spaced rounded projections equidistant from the center of the disk, said rounded projections being adapted to engage the recesses of the first mentioned disk.
